Interesting. I'm (quite obviously) not a subject matter expert. All I have to go on is the book from my old M-520 and my new Liberty. I imagine models changed in details through the years of development and what you may have is like a "M-380+", or something like that, dunno. Or an M-520 before they built secondary combustion capability into it. The book I have covers the M-520 and M-380 that were being produced at the time the book was current...and of course, the book has no date to be found on it anywhere. Rick

Rick / Fossil,

Just bought a house with an old, but gently used Lopi M-520.. in excellent condition. HAs the etched doors with the "duck" scene, like yours. Unfortunatelty, we didn't get a manual with it. Wondering if you could email me a PDF of the manual.... to jhirsche1<at>yahoo<dot>com ? Would be greatly appreciated... can post a pic of the stove if you like.

Also - previous owners had a dual-squirrel cage powered blower on it, with rheostat-adjustable fan speed. Having some trouble with the unit.. took it apart and cleaned it, but it squeaks, rattles, and doesn't put out like when we first moved in. Wondering if you have any suggestions on a replacement unit?

I have the same stove, same year. It is a 520. Has a sliding draft control lever on bottom of stove? The reason that you don't see the masonry secondary baffle inside is because it is easily removable. Once removed, the stove can really be stuffed with wood (not a good idea, although when young and dumb I did this!). There is a piece of angle iron that is supposed to run across the width of the fire box, then 5 or 6 fire bricks sit on top of that forming the baffle. You could easily make the piece of angle iron or have a piece cut for you, then buy the fire brick to fit on top. There should be tabs on each side of the fire box where the angle iron sits.

For the most part I love my 520. I have the double blower which is great, and brass doors with etching(lame). Mine is even worse than the wildlife scene as it is a grape vine with grapes... Always have wished I had the single door for better fire viewing. Glass stays clean if you run it at the right temp and use dry wood. This stove puts out some serious heat, and is fairly conservative with wood use considering. It is not going to be up to the new EPA standards I am sure, but still a great stove. Smoke-belching? Any stove will produce smoke if the oxygen supply is cut down enough (although this is not possible on some) and any stove will burn relatively smoke free if burned with plenty of oxygen (open draft). If you burn this stove where it should be burned (approx 300-350 degrees where flue exits stove) you will have the best results. The real question for any stove is how many BTU's can be utilized for a given unit of wood. My 520 would heat 1,000 sq feet no problem- it is currently heating about 1,500. I believe they were figured to put out 70-80,000 btu's or so. If you have the blower attachment it makes a HUGE difference in heat output. If you paid $300 or less you got yourself a fair deal, especially if it has a working double blower. Make sure there are no cracks or non-factory welds (unlikely but possible). If there are, get the stove looked at by a welder to make sure it is safe. Might need new seals around the doors too. I bought mine in 1994 for $450.00, and that was a good deal. Good luck- if anyone knows of a single door Liberty-type of same size as 520 for sale in WI, plz let me know!

I should clarify. The Liberty is essentially a 520 that has been fitted with the current EPA-listed secondary combustion system. The dimensions of the 520 and Liberty are the same - heck, even the dimension diagram for the Liberty on the LOPI website shows a 25 year old 520 just like yours! The double door went to single, but the cut-out in the stove is still the same size- a single door can be retro-fitted to an old 520. I talked to Lopi about this years ago. I just wish I could find a nice, cheap, used single door for sale! I wouldn't mind the elk in the mountains scene...or even the duck over the marsh!

Your old 520 will tend to produce way more smoke than the Liberty. The Liberty can't produce much smoke- it HAS to burn up to EPA standards. it is built that way. Smoke is essentially un-combusted wood. Your 520 WILL produce LOTS of smoke if you really damp it down, especially with a large load of wood that is not at or close to the "coal" stage, or wood that has not been seasoned and dryed. If you burn it around 350-400 degrees, you will not be smoking much out the flue, if at all. It is a good general balance between efficiency and BTU sequestration. A lot depends on chimney construction and design as well.

So is your stove up to EPA standards of the Liberty? No. Will it produce more smoke? Most likely, or if it doesn't, you will be burning more wood than you would with the Liberty, and the efficiency will be lower. Will it use more wood than the Liberty to "give-off" the same btu's? Yes. The real benefit to the 520 over other stoves of that vintage was the increase in efficiency due to the functional "seconary combustion" design, plus the quality and control was top-notch, still is.

To the guy looking for the squirrel-cage blower for the 520: I believe that the liberty blower will bolt on to your 520, although of a newer design, and will work. You better contact Travis Ind first to make sure though. You can buy them new from them. They would be pretty steep in price though.

That's really nice Kenny, way to rub it in. I'll have to take a picture of mine soon and post it on here- you can't beat a grape vine with a big bunch of grapes (sarcasm). I wonder what the people that paid extra for that (when it was bought new) were like... probably pretty interesting folks. Maybe it originated at a vineyard? Who knows!

I just bought a 1984 Lopi 520 was wondering if anyone ever found a pdf of the manual, would like to find clearances from non combustible walls.

Click to expand...

I gotta assume you mean minimum clearances from combustible walls. If you have a truly non-combustible wall (solid concrete, stone, or masonry with no combustible material of any kind in it or behind it), then there is no minimum required clearance.

I had a manual for the M520/M380, but I mailed it to member jhirsche some time back, since I no longer owned the stove. Don't have an electronic copy, sorry. Rick

On the back of the stove there is a label with clearances from combustable walls. But when I was looking at Lopi's website about the liberty and noticed reduced clearances from noncombustible walls. looking at the NFPA website I found reduced clearances from noncobustables walls for unlisted stoves and since I don't have a manual It is considered an unlisted stove but the clearances weren't to far of that from combustible walls. Just want to make sure everything is on the up and up.

Wow, just searched this thread out. I have posted about a stove I found on CL that appears to be a Lopi revere, and I will be getting a good deal on it if I choose to buy it from the guy tonight. I am trying to prepare myself for the possibility of it being an older stove. Did all these transitional and older Lopi stoves have double doors in the front? The one I am looking at has just one door and it's that distinctive looking door. THe pics are pretty awful though so it's hard to tell. A few revere owners thought it looked like their stoves, but a couple others had doubts on some details. I would post the CL listing again, but it just expired! Lucky I saw it when I did, lol!

So what ever happened to the thread's author---got that stove, finally posted pics, and then nothing..........or am I missing something? I wonder how he is with it a year later.........most likely went with something else....
I just picked up a Model 380 from April '84, haha.......it looks about in the same condition as Dominos did. I have no info on it other than the label on the back. This was the poor man's model? 'Smoking Dragon?' Oh boy.....thought I had a cool project to start. I just got my old Whitfield Advantage('88) running right and very nice, in the other part of our home.....hoping that would hold me over so I can work on this 350+# wood burning beast. Am I a fool??
Here's a pic or two. I hope maybe I can catch back some of your interest and get some feedback, whatever info/ideas, and maybe that manual is still floating around somewhere?? If you have an older LOPI I love to see some pics of it, or a link to your thread. If I get much showing of interest in this I may start another thread. So that will probably scare you guys out of saying anything, eh?
Yes, I very well may just have to go buy a new one............

Well, this will not let me post pics atm.....might be my comp, might be the sight......either way, I'll be back with pics.............

Oh, and I read somewhere here that this stove became the Endeavor--------but that is incorrect and it's what became the Liberty??

........do I sandblast it, or is there another way----I just got it in there tonight to warm up and was hoping to not have to drag it all out again.......
But I have the angle iron for the upper part where more brick go, new gasket/rope, brick, chimney kit and exterior pipe. I went all 6" on the chimney($90 for ea 36" section---$79 for 24", go figure) from the ceiling up; and well, this actually hasn't happened yet but is supposed to tomorrow or Monday for sure, if they got thier job completed that they're installing today. The wood stove is going where the ladder sit now---my pellet stove is in the other room there so the stacks will be about 15' appart-----the Advantage's stack opens up into a 10" ID from the three incher and is ALL double wall stainless (16' $$$)---must have had something else in there at some point, though this place was new in '01......... I am becoming the RamblingMan............yada yada(anybody have that handle??duh).
K..... er da pic----whatcha tink?

Ive just finished restoring an older lopi 520.I dont have a manual so I have a question or two.1st does lopi suggest putting fire bricks on top of the baffle<the piece of iron inside at a diagonal>the old one was warped and had a big hole through it.2nd,what REALLY cleans stove glass that is cloudy .3rd do you ever close the top vents?how bout the bottom vents,can you shut them down at night? back to that baffle,does the angled lip go up?down?front or back? If I knew how Id post pics.

addison: I am not sure enough to tell you any of the answers but somebody that did know said about putting the bricks up above to create a chamber like area. I haven't yet run my LOPI 380, so I cant say about the vents either, or how much you can dampen it down at night. My stove does have that angle piece with two slots for them in the upper area so it would set in there pointing East to West, and I am not sure if the lip goes forward or back: I haven't even tried to lay out the brick. One thing I can tell you for sure: these are awesome old stoves and I most definately want to get this one I have running. The steel is 5/16" thick and the craftmanship that went into these really shows----especially when you look at the welds and moving parts on some of the newer stoves.
Well, I hope somebody comes along that can answer your questions for you!! Good luck----would love to see some pics of your stove.

Burning Chunk: How'd the 380 rebuild turn out? I have a 380 and the top angle piece that holds firebricks up completely disinigrated and I had to toss it last winter. I finished the winter without the top bricks installed, but need to get this stove ship-shape before snow flies this fall. Any chance you have a picture of that angle piece that holds up the firebricks, or the dimensions? I need to make a new one to hold up the bricks.

Okay, firestarter, haha.......
I actually still need to paint it but plan to use it this year. I will get a pic of the iron piece you are referring to.....but I am thinking this one's is just like a heavy piece of angle iron. I was skeptical to run this stove last year due to all of the comments I recieved here about them being called a 'smoking dragon' amoung other things... I 'd love to hear about your and how it's performed. Have a pic??

Fred-
Here's a scan from the owners manual that shows the parts of my baffle that failed. I'll try to get some pictures posted of the actuall stove.

I don't know what year my stove is, but the owners manual has Oct 1986 printed on the front, so it must be newer than that. It's mounted inside the fireplace so I can't get a look at the tag on the back to see the model/date.

I'm sure that the newer stoves are more efficient than this 380, but I think labeling it a "smoking dragon" may be a bit harsh. Before the baffle in ours failed I felt that it did a good job of recapturing particulates. I'd alway start it with both dampers open, then after about 30 minutes close the bypass damper which caused a secondary burning of the emmisions. The first 30 minutes were as smokey as if it were an old stove without the secondary burn feature, but after that I could hardly ever see smoke from the pipe.

We live at 4600' and have used this stove as our only heat source in a 1500 sq ft house for the last two winters. I definately don't want to pay for a new stove, so my goal is to maximize the potential my "smoking dragon", Ha. Hopefully I can do it without breaking anything, or having to move it!

I haven't seen one of these, but looking at the drawing I'd say that the "brick retainer" looks easy enough to fab up with a few measurements from inside the stove. Probably 1/4" angle iron. Maybe 1"x 2"? It has a shorter piece of flat bar welded on the back. 1/4" x 1 1/4"? The back retainer looks a little more complicated. It's probably 2" x 2" angle, but it might need to be welded on. That would be easier with the stove emptied out and on it's back. As I said, I haven't seen anything but this drawing, but it looks doable.

I took some pictures and noticed that the hooks in front are turned inward 90-degrees from what is shown in the installation manual sketch. Seems suspious. I also remembered that when I removed what was left of the baffle frame this winter it had flat bar going down each side. I think it had flat bar across the back also, but don't realy remember how it all fit together. I definately remember that it had angle across the front, but can't remember if it had that little lip welded on. I suppose it's possible that the previous owner did some fabrication work on it also? Something else kinda suspisous is that the Installation Manual is titled 380/440/520, but the Operation and Maintenance Handbook refers to this stove as the "Flawless - Frestanding".
